Abstract:

Provides analysis of historic and current physical and biological conditions of the watershed. Hydrology concerns include maintaining and improving adequate water supplies, maintaining and restoring water quality, and improving overall conditions of streams, floodplains, and riparian ecosystems. Other topics include aquatics, upland forest vegetation, wildfire risk, botanical resources, noxious weeds, vertebrates, fire and fuels, non-forest vegetation, and rare plants.

Description:

271 pp. Tables, figures, maps, references, appendices.
"The document addresses primarily Umatilla National Forest lands within the watershed. The
primary exception is the aquatics analysis, which was based heavily on an extensive subbasin
summary of the entire Potamus subbasin completed by the Northwest Power Planning Council
(Gephart and Nordheim 2001)."
Map appendix is dated October 2004.

EA proposes vegetation and fuels management on about 10,000 acres to improve the health and vigor of the upland forest, and reduce the potential for future fires of uncharacteristic effects in upland forests. Includes commercial thinning of about 2400 acres, treatment of 40 acres of dead and downed woody material resulting from the 2000/2001 tussock moth outbreak, precommercial thinning of about 700 acres, treatment of surface fuels on about 10,000 acres, and reconstruction and maintenance of existing roads and construction of about 4 miles of temporary roads. Decision notice announces implementation of Alternative 4 with minor modifications, reducing big game vulnerability by not treating the existing satisfactory wildlife cover.

Proposes vegetation and fuels
management on about 13,900 acres to improve the health, and vigor of the upland forest, and reduce
the potential for future fires of uncharacteristic effects in upland forests through the reduction of
hazardous fuels and reduction of ladder fuels. Vegetation management treatments include commercial
thinning of about 2,218 acres, mechanical fuels treatment of 2,113 acres of standing dead and downed
woody material and reduction of conifer regeneration resulting from the late 1980s and early 1990s
spruce bud worm outbreak, noncommercial thinning of about 1,186 acres and treatment of surface fuels
on about 10,288 acres. Maintenance of existing roads (39 miles of open and 41 miles closed),
construction of a new system road for 2.2 miles, obliteration of 2.4 miles, and construction of about 3.6
miles of temporary road would be required for access and haul purposes.

The Proposed Action identifies a designated system of roads and trails that would be available for OHV
use. There would be a total of 290 miles of roads and trails available as motorized trails for OHV use.
Existing open and closed roads would be designated as an OHV system. New trails would be added to
provide connections to other trail systems on the Forest and to the Morrow/Grant County OHV Park.
